\begin{Description}\relax
Used to compute coordinates for additional rows or additional factors
in a multiple correspondence analysis.\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'mca':
predict(object, newdata, type = c("row", "factor"), ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] An object of class \code{"mca"}, usually the result of a call to \code{mca}.

\item[\code{newdata}] A data frame containing \emph{either} additional rows of the factors used to
fit \code{object} \emph{or} additional factors for the cases used in the
original fit.

\item[\code{type}] Are predictions required for further rows or for new factors?

\item[\code{...}] Additional arguments from \code{predict}: unused.

\end{ldescription}
\end{Arguments}
\begin{Value}
If \code{type = "row"}, the coordinates for the additional rows.


If \code{type = "factor"}, the coordinates of the column vertices for the
levels of the new factors.\end{Value}
